CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority of Taiwanese Invention Patent Application No. 109145390, filed on Dec. 22, 2020.

FIELD

The disclosure relates to a shoe, and more particularly to a moisture-permeable waterproof shoe.

BACKGROUND

Referring to FIGS. 1 to 3, a conventional sock shoe includes an inner sleeve 1, an upper 2 sleeved on the inner sleeve 1, a binding band 3, and a sole 4 fixed to a bottom part of the upper 2. The inner sleeve 1 defines a foot space 102, and has a sleeve top open edge 101 surrounding a foot space opening 103 of the foot space 102. The upper 2 has an upper top open edge 201 that corresponds to the sleeve top open edge 101 and that has the same height as the sleeve top open edge 101. The binding band 3 is fixed around the sleeve top open edge 101 and the upper top open edge 201 to bind them together.

Referring to FIG. 4, in combination with FIG. 3, in order to maintain the stability of the conventional sock shoe when worn by a user, the sleeve top open end 101 thereof cannot be located lower than an ankle of the user to prevent a width (W) of the foot space opening 103 from becoming too large, thereby preventing a heel of the user from slipping out of the conventional sock shoe. Since the width (W) of the foot space opening 103 is smaller than that of a normal shoe, and since the inner sleeve 1 has a certain structural toughness, the user cannot greatly pull the sleeve top open edge 101 to widen the foot space opening 103 when wearing the conventional sock shoe, so that an entry angle of a foot of the user into the foot space 102 through the foot space opening 103 is quite limited. At first, only less than half of the user's foot can be inserted into the foot space 102, after which the user spends a lot of time and effort to insert the sole of the foot into the foot space 102, and finally, a heel portion of the conventional sock shoe is pulled upward with force to fit the remaining portion of the foot into the foot space 102. Thus, it is inconvenient to wear the conventional sock shoe.

Furthermore, the sleeve top open end 101 of the conventional sock shoe cannot be located above the ankle of the user as it will cause the width (W) of the foot space opening 103 to become too small which will hinder the wearing of the conventional sock shoe. Hence, the conventional sock shoe cannot cover well the ankle of the user, thereby affecting the comfort during the wearing thereof.

SUMMARY

Therefore, an object of the present disclosure is to provide a moisture-permeable waterproof shoe that can alleviate at least one of the drawbacks of the prior art.

Accordingly, a moisture-permeable waterproof shoe of this disclosure includes a shoe-shaped inner sleeve, an outer sock body, a connecting layer and a sole. The shoe-shaped inner sleeve includes a moisture-permeable waterproof layer located on an outer side thereof, defines a foot space having an open top end and a closed bottom end, and has an inclined annular top edge inclining downwardly from a front side to a rear side thereof. The foot space has a foot space opening surrounded by the inclined annular top edge.

The outer sock body includes a main sock body portion, an insertion portion and an annular sewing portion. The main sock body portion corresponds to the shoe-shaped inner sleeve, is sleeved on the shoe-shaped inner sleeve, and has an annular top edge. The insertion portion extends upwardly from the annular top edge of the main sock body portion. The annular sewing portion extends downwardly from the insertion portion to the foot space and is fixed to an inner surface of the shoe-shaped inner sleeve. The annular sewing portion has a bottom edge lower than the inclined annular top edge.

The connecting layer is fixed between the shoe-shaped inner sleeve and the outer sock body. The sole is fixed to a bottom surface of the main sock body portion.

The insertion portion is higher than the inclined annular top edge, defines an insertion opening communicating with the foot space, and has a front ear, a rear ear opposite to the front ear, and two side portions connected between the front and rear ears. The front ear has a front ear body portion, and two front wing portions extending rearwardly and respectively from left and right sides of the front ear body portion. Each front wing portion has a top edge that inclines rearwardly and downwardly from a top edge of the front ear body portion. The rear ear has a rear ear body portion corresponding to the front ear body portion, and two rear wing portions extending forwardly and respectively from left and right sides of the rear ear body portion and corresponding to the two front wing portions.

Referring to FIGS. 11 to 13, to wear the moisture-permeable waterproof shoe 100, a user simply pulls apart the front ear 24 and the rear ear 25 of the insertion portion 22 to make the width (W2) of the insertion opening 27 larger than the width (W1) of the foot space opening 151 and to increase an entry angle of a foot of the user into the insertion portion 22 through the insertion opening 27. At this time, since the width (W1) of the foot space opening 151 of this embodiment is greater than the width (W) of the foot space opening 103 (see FIG. 3) of the conventional sock shoe, the user can directly insert approximately three quarters of his/her foot into the foot space 15 of the shoe-shaped inner sleeve 10 at the beginning, and then pull upward the front ear 24 and the rear ear 25 to insert the entire foot easily and smoothly into the foot space 15 with less effort. Afterwards, pulling of the front ear 24 and the rear ear 25 may be released to switch them back to the non-pulling state so as to cover the user's ankle. In addition, as shown in FIG. 14, the user can extend the second strap body 422 around the rear side of the rear ear 25 to releasably connect the second connecting member 423 to the first connecting member 413, and tightness of the rear ear 25 against the user's heel can be adjusted through the second strap body 422.

From the aforesaid description, the advantages of this disclosure can be summarized as follows:

1. Through the configuration of the inclined annular top edge 16, which inclines downwardly from the front side to the rear side of the shoe-shaped inner sleeve 10 so that the width (W1) of the foot space opening 151 of the shoe-shaped inner sleeve 10 can be effectively increased, and through the configuration of the front and rear ears 24, 25 of the insertion portion 22 of the outer sock body 20, which can be pulled apart from each other so as to make the width (W2) of the insertion opening 27 greater than the width (W1) of the foot space opening 151 so that the entry angle of the foot of the user into the foot space 15 through the insertion opening 27 can be increased, the moisture-permeable waterproof shoe 100 of the present disclosure can be easily worn on or removed from the foot of the user as compared to the conventional sock shoe.

2. Through the configuration of the front and rear ears 24, 25 of the insertion portion 22 of the outer sock body 20, the front and rear ears 24, 25 can compensate for the low position of the inclined annular top edge 16 from the ankle of the user. In comparison with the conventional sock shoe, the moisture-permeable waterproof shoe 100 not only can provide easy wearing and removal thereof, but also can improve comfort during wear thereof through the front and rear ears 24, 25 which can cooperatively cover the user's ankle. In addition, with the rear ear 25 serving as a blockage to prevent the user's heel from slipping out of the shoe-shaped inner sleeve 10, stability of the moisture-permeable waterproof shoe 100 when worn by the user can be maintained.

3. Through the cooperation of the first and second tightening plates 41, 42, the second strap body 422 can extend around the rear side of the rear ear 25 to releasably connect the second connecting member 423 to the first connecting member 413. Therefore, the user can adjust the tightness of the second strap body 422 against the user's heel to effectively prevent his/her heel from easily slipping out of the shoe-shaped inner sleeve 10. This can further improve the stability of the moisture-permeable waterproof shoe 100.
